A Texas mattress company has issued an apology after viewers were outraged by a 20-second advertisement which depicts two stacks of twin mattress getting knocked over in a mimicry of the 2001 attack on the World Trade Center. The ad was created by the San Antonio branch of Miracle Mattress and shows the store manager, Cherise Bonanno, asking, “What better way to remember 9/11 than with a Twin Towers sale?” After two employees knock over the mattresses, Bonanno says: “We’ll never forget.”
